Also... selecting text should not COPY the text into the clipboard and then remove the selection. Should be select, followed by the Copy or CNTRL-C.
that completely depends on what you are used to. it's a commonly used copying technique in e.g. unix/linux terminals. I don't see anything wrong with the current way. for windows users who have never encountered such a selection method it might be a bit tricky at first, but since the text window doesn't work with a cursor the 'regular' (windows) way of copying would be harder to do.
